Leroy Sane is certainly a very talented footballer. But he doesn't have the consistency to showcase his talents. If he wants to play for a team at the level of Bayern Munich permanently, he has to show consistent performances. If he doesn't accept Bayern Munich's conditions, he will continue to have the same problems in teams at the level of Bayern Munich. I think he should stay at Bayern Munich and improve his performances to a more consistent level. If I were him, I would try to stay at Bayern Munich. Because Bayern Munich are one of the best clubs not only in Germany but also in Europe and the world.
In my opinion, Leroy Sane's performance is not bad, it just can't be said to be very good, there are things he still needs to improve with Bayern Munich. From his 27 appearances last season with Bayern Munich in the Bundesliga, he recorded 8 wins and recorded 11 assists, in my opinion that is a contribution he can make to this big club in Germany. His contract with Bayern Munich will end in 2025, which means he has one more season left. But so far I haven't heard whether there will be a contract extension offer from Bayern Munich or not.
However, I suspect that Bayern Munich will probably consider first whether they will extend his contract or not. Maybe next year there will be a decision from Bayern Munich about Leroy Sane's future. Next season, I think he will still be with Bayern Munich and help Bayern Munich regain the throne that Leverkusen managed to coup last season. Unless Bayern Munich gets a tempting offer from another club.
